Any experience with Nokia Ad Exchange

Does anyone here have experience with Nokia Ad Exchange… https://nax.nokia.com ?

They act as a mediation network and claim to have 120 Ad networks registered with them.

Pretty much the same as Inneractive: App Monetization. Simplified - Home I believe. They have very good support, also they have sdk for all platforms. I tried them out about a year ago when I only had educational apps for Finnish and Swedish users and the revenue was very low… however the revenue for those apps are still very low today on other ad networks so I can’t really say if they pay good.
